Q: when solar panels have served their purpose, what is done with them?: Solar water heating panels can be salvaged for the copper and aluminum in them. Unless there's catastrophic damage, solar electric panels only weaken with time. Given that serious panels have a life of over 25 years, it's debatable whether anyone would want them after they've served their useful life, any more than someone would want a 386 computer from 985 running at 6 MHz. The glass and metal could be recycled, but the acutal solar cells I think would be thrown away. Contemporary panels are made ROHS compliant with zero lead, so are not especially toxic.

Q: How many kilowatts? Would it be enough to power my electric heat?Does one panel cost about $2000.?: I doubt it'd supply your heat. Anything involving electric heating uses tons of energy. Also, keep in mind that you don't just need a panel but also a DC to AC converter.

Q: Can solar panels be installed on schools or universities?: Yes, solar panels can definitely be installed on schools or universities. In fact, many educational institutions are increasingly adopting solar energy as a sustainable and cost-effective solution to meet their electricity needs. By installing solar panels, schools and universities can reduce their carbon footprint, save money on energy bills, and provide a valuable educational opportunity for students to learn about renewable energy.

Q: Can solar panels be used in areas with frequent power outages?: Yes, solar panels can be used in areas with frequent power outages. Solar panels generate electricity from sunlight, which means they can continue to produce power even when the main grid is down. However, for uninterrupted power supply during outages, it is important to have an energy storage system, such as batteries, to store excess energy generated during the day for use at night or during power outages.

Q: For those solar panels that you install on your rooftops, do they generate electricity when it's cloudy? And if yes, how much electricity does it generate compared to sunny days? For example...like only 25% electricity generated compared to sunny days?: No, silicon photovoltaics reacts to a very specific frequency of infrared light which matches the bandgap energy of it's outer electron shell. This frequency is reflected by clouds. However, thermal solar collectors such as evacuated tube collectors can function under cloudy skies albeit at a lower rate and there is at least one hybrid photovoltaic and thermal panel designed to take advantage of this.

Q: Solar panels single crystal and double crystal in the rain which is easy to use: At present, monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.

Q: i have a 50 watt 2 Volt solar panel..Will it can switch on directly a car head light on a sunny day??? How much head lights it can support on a bright sunny day??? if its cloudy then can it run a single Head light???? i have no batteries just want to connect a car Head light directly to solar panel.: It should illuminate two auto headlights on a sunny day, if it really generates 50 watts at 2 V. On a cloudy day, I don't know. It depends on how cloudy it is.

Q: Can solar panels be installed on the ground instead of a roof?: Yes, solar panels can be installed on the ground instead of a roof. Ground-mounted solar panels are a viable alternative when roof space is limited or unsuitable for installation. Ground installations offer flexibility in panel orientation and tilt, making it easier to maximize solar energy production. Additionally, ground-mounted systems are often easier to maintain and can be expanded more easily than roof-mounted ones.

Q: Can solar panels be used to power a hospital?: Yes, solar panels can be used to power a hospital. Solar energy can be harnessed through solar panels to generate electricity that can be used to power various equipment and facilities within a hospital, including lighting, medical devices, ventilation systems, and more. Using solar power can help reduce reliance on traditional energy sources, lower operating costs, and contribute to a more sustainable and environmentally-friendly healthcare system.

Q: Can solar panels be used in conjunction with energy-efficient appliances?: Yes, solar panels can definitely be used in conjunction with energy-efficient appliances. In fact, pairing solar panels with energy-efficient appliances is a great way to maximize the benefits of renewable energy and reduce overall electricity consumption. By generating clean electricity from the sun, solar panels can power energy-efficient appliances, resulting in significant energy savings and a more sustainable lifestyle.
